Discriminant Analysis of Geographical Origin of Cork Planks and Stoppers by Near Infrared Spectroscopy

Abstract: The objective of this study was to assess the potential of visible and near infrared spectroscopy (VIS+NIRS) combined with multivariate analysis for identify

“…The results reported by Espinoza et al [50] indicate that NIRS can be used as an effective tool to distinguish between pure pine species and suggest that it will also distinguish hybrids from their parents. Prades et al [51] assessed the potential of visible-NIR spectroscopy for identifying the geographical origin of cork. They found good classification results.…”

“…La recogida de espectros y el análisis quimiométrico cuantitativo se realizaron con el software WinISI II (Versión. 1.50) siguiendo la misma metodología de estudios previos (Prades et al 2010, Prades et al 2012). …”

“…Los espectros de las planchas y laterales son bastante parecidos y el espectro medio de las bases tiene menor intensidad de absorción -log (1/R). Estas variaciones tienen su origen en las diferentes medidas de las ventanas y secciones del corcho utilizadas en cada caso (Prades et al 2012). El espectro medio de las láminas se sitúa entre ambos, y aunque la superficie de absorción es muy superior (51,75 cm 2 ) y la sonda utilizada es diferente, las bandas de absorción son las mismas.…”

“…The potential of this technology as a method for predicting the geographical origin of cork planks and stoppers has been demonstrated (Prades et al 2012). It allows continuous quality control of moisture content in cork stoppers while simultaneously obtaining other parameters such as chemical components (waxes and total polyphenols) along with physical and mechanical parameters (density, extraction force and compression force) (Prades et al 2014).…”
